Moreover, high risk prisoners used cigarettes/day more (۱۴.۸۷±۱۱.۵۵ vs. ۹.۷۱±۹.۰۹, P<۰.۰۰۱), but both groups were not different in term of the marital status (P=۰.۵۱۹), educational level (P=۰.۶۶۲), job (P=۰.۳۹), and nationality (P=۰.۳۴۲).Conclusion: Our results showed that none of the high-risk prisoners for TB had positive test.
